ことを特徴とする絶縁高所作業車の操作装置。In an aerial work vehicle that has a work platform at the tip of an insulated boom, a signal is output from each potentiometer in proportion to the operation of a control lever provided on the work platform, and this signal is sent to each A/D.
A converter converts the digital signal into a digital signal, a parallel/serial converter converts the digital signal into a serial signal, a digital optical transmitter converts the serial signal into an optical signal, and the optical signal is provided along the boom. The optical signal is sent to a digital optical receiver installed on the vehicle body side via a single optical fiber cable, and this digital optical receiver converts the optical signal into a serial signal, and this serial signal is converted into a parallel signal by a serial/parallel converter. This parallel signal is converted into four analog signals by each D/A converter, and each analog signal is amplified by each amplifier to control each proportional control valve. Work vehicle operating device.
